Compressed Air Filters

Meeting your air quality requirements
Properly sized and selected Kaeser filters in conjunction with the appropriate dryer will remove harmful contami-nants. This allows the compressed air system to deliver the quality of air required—whether it’s plant, instrument, or breathing air.
High performance filters and separators
Engineered and developed using the latest innovations and manufacturing techniques, Kaeser filter housings are designed with larger flow areas to ensure the lowest pres-sure drop and provide easier installation, operation, and maintenance. The result is consistent product quality with minimized operating costs.
Why treat compressed air
Ambient air contains contaminants that are drawn into the compressor. These contaminants are concentrated during compression and can easily pass into the com-pressed air system. A typical compressed air system is contaminated with abrasive solid particles such as dirt, rust and pipe scale, compressor lubricants, condensed water droplets, and oil and hydrocarbon vapors.
Contaminated compressed air systems increase operating costs by reducing efficiency. This results in damaged pneumatic equipment, higher maintenance and repair costs, reduced production (due to downtime), and increased product rejections.
Superior filtrationProper filtration is necessary to ensure consistent air quality, but with it comes pressure drop. Every 2 psi of pressure drop increases power costs by 1%. Kaeser filters remove more contaminants with less pressure drop for lower operating costs. With a complete selection of application-specific filter types, sizes, technical service, and support, Kaeser offers a customized solution for all of your compressed air quality needs.

Minimized pressure losses
The generously-sized connection flanges help keep pressure losses to an absolute minimum. Additionally, all particulate and coalescing filters (KB, KD, KE) come standard with a differential pressure gauge to check filter efficiency at a glance.
High efficiency carbonmatting
Unlike the granular material used in many other filters, Kaeser’s KA filters use carbon impregnated mat-ting to prevent channeling while also reducing pressure drop. This highly absorptive matting is also effective at preventing particles from escaping.
Deep pleated filter elements
Kaeser’s KB, KD, and KE dust and coalescing filter elements feature deep-pleated filter elements wrapped in stainless steel cages. The extra large surface area ensures superior filtration, increased efficiency, and reduced pressure drop.

Global StandardsISO 8573.1:2010 was developed by ISO (International Organization for Standardization) as a reference to help facility engineers specify compressed air quality for solid particulates, humidity, and oil.
A typical pharmaceutical plant, for example, might have a compressed air specification of ISO Quality Class 1.2.1. as shown outlined in the specifications below.

Proper Filter SizingTo find the maximum flow for a filter size at pressures other than 100 psig, multiply the rated flow by the Correction Factor corresponding to the minimum pressure at the inlet of the filter.
Do not select filters by pipe size. Use flow rate and operating pressure.
